On the one hand, as the values of family values change, the value of self-reliance on retirement is fading, and the importance of personal financial management and retirement finance design for the need of retirement measures to solve their old age is increasing.

In addition, real investors do not only invest in one asset but also invest in various assets to own a portfolio. In a broad sense, a portfolio refers to a combination of assets, but in a narrow sense means a combination of financial assets such as stocks and corporate bonds traded in the stock market. When constructing a portfolio, investors seek to obtain the best risk-return relationship, just as they invest in individual assets. Therefore, measuring portfolio risk and calculating expected returns are the most important factors in selecting a portfolio.

However, in general, individuals should have professional financial knowledge and strategic thinking to manage their assets as well as tax and regulatory provisions for financial diagnosis and retirement design. In addition, it was difficult to obtain and analyze information on inflation, interest rate, stock price index, real estate price index, exchange rate, crude oil price, economic growth rate, trade balance, consumer investment propensity and unemployment rate, and financial total taxation system.

So, most individuals are consulted by a specialist for their own assets to design an investment, pay a considerable amount of money, or do not recognize the right risk, "

1 is a block diagram of a life cycle-based retirement financial design system according to an embodiment of the present invention.

Referring to FIG. 1, a lifecycle based retirement financial design system according to an embodiment of the present invention will be described.

1, the life cycle-based retirement financial planning system according to an embodiment of the present invention includes a data input unit 110, an income level calculation unit 120, a human capital calculation unit 130, (140), a risk asset allocation calculation unit (150), and a tax benefit asset investment allocation calculation unit (160).

The data input unit 110 stores the first level of income level L (t), the first level of financial asset F (t), the first level of consumption level C (t)), a retirement pension, a national pension, a calculated amount of money to be paid, wage information of a company and an industry to which the subscriber belongs, real estate information, and debt information.

The data input unit 110 receives the income level L (t) at the first time point from the database 211 of the customer information database 111 or the external credit information system 210 of the lifecycle-based retirement financial design system, (T), the consumption level at the first time point (C (t)), the retirement pension, the national pension, the calculated amount of money transferred, the wage information of the company and the industry to which the subscriber belongs , Real estate information, and debt information.

More specifically, the income level L (t) at the first time point corresponding to the current or future time when the data input unit 110 is input is calculated using the current wage information and the wage increase rate of the enterprise in the case of the retirement pension subscriber In the case of a general subscriber, the current wage information is input directly from the customer or the current wage information is estimated by using external data, and the future wage is estimated by applying the average wage increase rate of the enterprise or industry to which the subscriber belongs do. The consumption level (C (t)) at the first time point at which the data input unit 110 is inputted defines a similar group in consideration of the engaged industry, age, and years of service of the subscriber, The average consumption information that can be collected including the card information of the military, or the financial data of the National Statistical Office may be used. The retirement pension received by the data input unit 110 is calculated by using the current number of service years of the subscriber, the median settlement date, and the statutory retirement age, and the national pension is calculated based on the income information and the wage increase rate of the subscriber, Method, or may bring information directly from the national pension site under the consent of personal credit information.

The estimated amount of money received from the data input unit 110 is an amount to be paid as retirement funds during the accumulation period. If the estimated future amount of the retirement annuity and the national pension is subtracted from the estimated future consumption level, The size of the investment assets to be accumulated. In order to accumulate these assets, the amount to be paid annually is calculated to reflect the expected return on assets. In this case, assuming that the current consumption level is maintained in the future, the consumption level of current retirees is divided into the top 10%, 20%, etc., Estimate the consumption level. However, since the current elderly people think that they are not ready for retirement, they are calibrated with the opinion of the experts because they may be underestimated to the target retirement standard level. For this purpose, data of the National Statistical Office and related research data are used.

FIGS. 2 to 5 are diagrams for explaining a life-cycle-based retirement financial designing method according to an embodiment of the present invention.

Hereinafter, a lifecycle-based retirement financial designing method according to an embodiment of the present invention will be described with reference to FIGS. 2 to 5. FIG.

Unlike the prior art model, which provided an asset allocation plan only with financial assets, the present invention estimates and capitalizes the entire lifetime income flow of a single individual to aggregate the financial assets to present an optimal allocation of assets There are features.

The data input unit may include a first level of income level L (t), a first level of financial asset F (t), a first level of consumption level C (t), a first level of income level L ), The retirement pension, the national pension, the calculated amount of money to be paid, the wage information of the company and industry to which the subscriber belongs, the real estate information, the debt information, and the like, (210), a financial capability (220) including a consumption level at a first point of time, and provides a financial ability (220) including an expenditure information Information 230, estimated retirement amount 240, and the like. At this time, as shown in FIG. 2, information such as the necessary retirement funds 250 and the retirement funds 260 may be displayed together.

At this time, the data input unit receives from the database of the customer information database or the external credit information system of the life cycle-based retirement financial planning system the income level L (t) at the first time point, the financial asset at the first time point At least one of the consumption level (C (t)) of the first time, the retirement pension, the national pension, the calculated amount of money, the wage information of the company and industry to which the subscriber belongs, Can be input.

In addition, the consumption level (C (t)) at the first time point at which the data input section receives the input is defined by taking into account the occupation industry, age, and years of service of the subscriber, The average consumption information that can be collected including the card information of the Korea National Statistical Office or the financial welfare data of the National Statistical Office can be used. In addition, the estimated amount of money received by the data input unit is the amount to be paid as retirement funds during the accumulation period. If the estimated future amount of the retirement annuity and the national pension is subtracted from the estimated future consumption level, The amount of investment assets to be achieved. In order to accumulate these assets, the amount to be paid annually is calculated to reflect the expected return on assets. In this case, assuming that the current consumption level is maintained in the future, the consumption level of current retirees is divided into the top 10%, 20%, etc., Estimate the consumption level. However, since the current elderly people think that they are not ready for retirement, they are calibrated with the opinion of the experts because they may be underestimated to the target retirement standard level. For this purpose, data of the National Statistical Office and related research data are used.

Hereinafter, a configuration for searching for the proportion of risk assets that maximize the size of the total assets (human capital + financial asset) utility as of the point t (t + 1) at the time t during the accumulation period of the present invention will be described. On the other hand, the term t refers to the time from the present to the age of retirement (present = t = retirement age).

The income level calculation unit calculates the income level of the subscriber using the first time income level (L (t)), which is the income level of the subscriber at the first time point, and the pay information of the company and industry to which the subscriber belongs, L (t + 2), ..., L (t + n) from the second point of time until retirement (1 ≤ n ≤ Nt, N: earning period).

More specifically, when the average wage increase rate using the age and the number of years of service of the subscriber is not input, the income level calculation unit calculates an income level flow from the second time point to the retirement time point using the following equation (1) L (t + 1), L (t + 2), ..., L (t + n)) are calculated (1 ≤ n ≤ Nt, N: accumulation period).

[Equation 1]

* ε? (L) =? ₁ *? (S) +

* ε

L (t + 1) = L (t) * exp (? (L) +? (L) *?

In this case, ρ ₁ is corr (ε (L), ε (S)), ε (S) and ε are stock random variables and general random variables, L (t + 1) (L) is the standard deviation of the expected wage growth rate of the industry to which the subscriber belongs, ε (L, t + 1) is the wage growth rate at time t + 1, The random variable is a normal distribution with an average of 0 and a variance of 1.

Alternatively, when the income level calculation unit receives the average wage increase rate using the age and the years of service of the subscriber, the second time income level L (t + 1) is calculated using the following equation (2).

&Quot; (2) "

* ε? (P) =? ₂ *? (S) +

* ε

(P, t + 1)) L (t + 1) = L '(t +

In this case, P is the inflation rate, ρ ₂ is the corr (ε (P), ε (S)), ε (S), ε are the stock random variable and the general random variable, (T) is the standard deviation of the expected inflation rate, and L '(t + 1) is the wage reflecting the promotion rate of the company or industry to which the subscriber belongs .

L (t + 2), ..., L (t + n)) from the second time point to the retirement time point (1 ≦ n ≦ (T + 1)), which is human capital one year after the first point in time, based on a value obtained by adding the present value of the time (Nt, N: accumulation period). At this time, the human capital calculation unit can receive the average loan interest rate information from the Korean Federation of Banks based on the individual's credit rating, and use it as a discount rate.

That is, the human capital calculation unit calculates the income level flows L (t + 1), L (t + 2), ..., L (t + n) until the retirement time after the calculated second point ≦ n ≦ Nt, N: accumulation period), and calculates the future wage for each age by summing all the values of the future wage discounted at the time t + 1 as a loan interest rate based on the subscriber's credit rating, Calculate the capital (H (t + 1)).

(T + 1), L (t + 2), ..., L (t + n) from the calculated second point of time to the retirement time (T + 1)) is calculated by applying the following equation (3) to the value obtained by adding (1? N? Nt, N: accumulation period)

&Quot; (3) "

H (t + 1) =

은 가입자의 신용등급별 대출금리이다.In this case, H (t + 1) is the second time human capital, L (t + i) is the income level flow until retirement after the second time point,

Is the lending rate for each subscriber's credit rating.

The financial asset calculation unit then removes the consumption level C (t) at the first time point from the sum of the first time income level L (t) and the financial asset F (t) at the first time point (T + 1)), which is the financial asset at the second time point, by multiplying a value by the principal amount obtained by investing in the risky asset and the risk-free asset.

More specifically, the financial asset calculation unit calculates the second-time financial asset F (t + 1) using the following equation (4).

&Quot; (4) "

In this case, F (t + 1) is the second time point financial asset, S (t + 1) is the risk asset size at time t + 1 and follows the geometric Brownian motion, F (t) (T) is the first time income level, C (t) is the t-point consumption level, x (t) is the risk weighted asset weight, (T) is the standard deviation of stock returns, ε (S) is the stock random variable, r (f) is the risk-free asset return and x (t) is the proportion of risky assets (0 ≤ x (t) ≤ 1).

Thereafter, the risk asset allocation calculation unit calculates a risk asset (the amount of risk) that maximizes the utility value by applying a utility function to the second time human capital H (t + 1) and the second time point financial asset F Calculate the specific gravity (x (t)). (X '(t)) is calculated by calculating the weighted sum of the retirement pension and the national pension against the transfer amount calculated on the calculated risk amount of assets (x (t)) to determine the final risk-efficient asset allocation plan do.

In more detail, the asset allocation calculator may calculate the risk asset weight x (t) using Equation (5) below.

&Quot; (5) "

x (t) =

a<1 또는 U(W)= ln(W)로서 W≥0이고 a=1이다.In this case, x (t) is the risk asset weight, F (t + 1) is the second time point financial asset, H (t +

a <1 or U (W) = ln (W) where W? 0 and a = 1.

In Equation (5), a power utility function is used as the utility function U (W), but various other functions can be applied.

In order to determine the weight of the portfolio, we first determine the allocation of assets such as stocks, bonds, and principal guarantee products, and then select financial products.

3 is a graph showing an expected utility size 320 to which the proportion of risky assets (x (t): 310) and the proportion of risky assets (x (t)) calculated as described above are applied, wherein the horizontal axis represents the age of the subscribers , The vertical axis (left) is the ratio of the proportion of risky assets, and the vertical axis (right) is the size of utility.

More specifically, the proportion of risky assets (x (t): 310) represents the proportion of risky assets to maximize the utility value, and the expected utility size (320) ) Represents the utility value of the asset at time t + 1.

For example, from 20 to 45 years of age, the share of stock should be 100%, which will increase the asset size of the next period and maximize utility value.

After calculating the proportion of risk assets (x (t)) as described above, the ratio of the sum of the retirement pension and the national pension to the calculated amount of money transferred to the calculated proportion of risk assets x (t) (X '(t)) to determine a risk-efficient asset allocation plan.

&Quot; (6) &quot;

Bond = z (t)%

Flowability = min (y (t)%, 1 - z (t)%) = u

X (t)% = min (x (t)%, 1 - z (t)

More specifically, the ratio of risky assets is x (t)%, liquidity is y (t)% (= 1-x (t)%) and retirement pension + national pension / (T)% = x (t)% = 100 (t)% = z (t)%, and the strategic asset allocation plan during the accumulation period is as shown in Equation %. At this time, the national pension plan and the retirement pension plan are structured to determine the allocation of assets assuming bonds.

Thereafter, when the amount of taxable asset investment allocation calculation tax portion is distributed to another product group such as taxable eligible product, new pension savings product, non-taxable product, general product, etc., It is the process of finding the optimal weight. For this purpose, the income tax deduction for retirement and the tax payable at the time of retirement are calculated, and the net tax benefit (sum of tax benefits plus sum of tax payments) is calculated We find the weight of each product to maximize and provide the final strategic asset allocation plan by linking with the risk-efficient asset allocation plan of the fifth stage in Matrix form.

Also, the pension benefit asset investment allocation calculation unit distributes the calculated investment amount to other product groups such as taxable eligible products, new pension savings products, non-taxable products, and general products, and provides the distribution result to the external terminal.

In more detail, the Tax Benefit Asset Investment Allocation Calculator calculates the applicable tax rate using the income level and financial asset at the first time point of the subscriber's current or future subscription to calculate the incurred tax, Apply to current tax law using MDSS data. However, if the customer directly inputs or obtains personal credit information agreement, more accurate income and assets can be applied.

Also, the Tax Benefit Asset Investment Allocation Calculation Department calculates the income deduction benefit until the retirement of the subscriber. For example, if the subscriber is 45 years old and the applicable tax rate is 24%, you can get the benefit of 480,000 won deductible by investing 2,000,000 won in the deductible product. Therefore, when you retire at age 55, It is applied to the growth rate of 3%, and it is calculated as the future value up to 55 years old.

On the other hand, the Tax Benefit Asset Investment Division calculates the applicable tax rate by estimating the amount of annuity received and the amount of assets received every year during the pension receiving period, and calculates the tax to be incurred. Calculate the tax that will be incurred in the present.

 The Tax Benefit Asset Investment Allocation Calculator finds the share of the distribution of the different product groups as the tax benefit that maximizes the net tax benefit (the sum of the above tax benefits - the sum of the above tax payments) converted to the monetary value at the point of retirement.

As shown in FIG. 4, the tax benefit asset investment allocation calculation unit allocates 420 the amount 410 to be invested within the accumulation period, to the income-deductible product and the non-income-deductible product calculated as described above 420, And provides a result 430 to the user or subscriber in the form of a recommended portfolio through an external terminal.

Therefore, according to the present invention, as shown in FIG. 5, not only a lifecycle customized portfolio including an earning earning period, an earning period, a retirement preparing period, and a pension asset distributor is provided, but also a maximized savings- It is possible to provide a portfolio that is optimized for personal investment propensity while increasing actual pension amount.

In the foregoing detailed description of the present invention, specific examples have been described. However, various modifications are possible within the scope of the present invention. The technical spirit of the present invention should not be limited to the above-described embodiments of the present invention, but should be determined by the claims and equivalents thereof.
